harris 算法，可以检查角度，就是角点检测-Harris algorithm, can check the angle, that is, the corner point detecting

数字图像中尖端点检测，采用了Harris算法，然后运用susan算法思想进行改进，使用时后面if程序的一些条件要适当改一下-Digital image edge detection, using the Harris algorithm, and then use thought susan algorithm is improved when you use the latter procedure if a number of conditions to change what should
